CVE-2026-59276
Timing Attack via Non-Constant-Time Comparison of Sensitive Values
CVSS Score
5.9
EPSS Score
0.0%
EPSS Percentile
0th
Several components in Spring Security compare security-sensitive values using standard string equality (String.equals()) rather than a constant-time comparison. Because String.equals() returns as soon as it finds a differing character, the time taken to reject an incorrect value is proportional to the number of leading characters that match the expected value.
